I've seen a few posts comparing the M2500 material (which I know everyone on avsforum loves) against the Da-Lite High Power. I think I'd like to go with a very large screen for my 600 lumens DLP projector, so I'm considering going to a high gain screen (probably about 130" diagonal). I would very much prefer to go with a pull-down screen; I can't have a permanent wall mount in my room.
Am I right that any screen with the M2500 suddenly becomes much more expensive than the Da Lite Hi Power, since the M2500 is only available on Draper's tab tensioned screens, while the High Power is available even on DaLite's inexpensive pull downs?
My projector is floor mounted (actually about 30" off the floor, which will be even with the bottom of the screen in a room with 10 ft ceiling). Is there something about the "retro-reflectivity" of the High Power material that makes it preferable to the M2500 in this situation? (I've read comments that you have to go with a ceiling mounted projector with the M2500. Was that because it's not "retro-reflective"?)
I've read an October post by Thomcat that gave a pretty positive review of the High Power screen, in a room situation very much like mine. Does anybody else have experience, good or bad, with the High Power material?
